the relationship between live body weight, body length, girth circumference, animal hight, upper, middle as well as lower width of fat-tail, fat-tail length, fat-tail gap length, fat-tail depth and fat-tail circumference along with fat-tail weight were determined using records of 731 loribakhtiari sheep. principal component and least square analyses were applied to solve the collinearity instab...

In this work, chemical oxidation was used to polymerize conjugated polymer "Polypyrrole" at room temperature Graphene nanoparticles were added by in situ-polymerization get (PPY-GN) nano. Optical and Electrical properties studied for the nanocomposites. optical of nanocomposites UV-Vis spectroscopy wavelength range (200 -800 nm). The result showed absorption spectra normally determined that max...

Lead halide perovskites possess high photoluminescence (PL) efficiency and strong electron-phonon interactions, therefore optical cooling using up-conversion PL has been expected. We investigate anti-Stokes from green-luminescent ${\mathrm{Cs}}_{4}{\mathrm{PbBr}}_{6}$, whose origin is attributable to ${\mathrm{CsPbBr}}_{3}$ nanostructures embedded in a ${\mathrm{Cs}}_{4}{\mathrm{PbBr}}_{6}$ cry...

Zinc sulfide (ZnS) films were deposited through a simple and low cost spray pyrolytic technique using mixed aqueous solutions of zinc nitrate and thiourea. The structural and optical properties of these films were investigated as a function of initial (Zn:S) molar ratio in the precursor solution, which varied between (1:1) and (1:3). X-ray diffraction (XRD) analysis revealed that wurtzite...

A general semiconductor-independent two-dimensional character of the carrier distribution in top-gate polymer field-effect transistors is revealed by analysing temperature-dependent transfer characteristics and the sub-bandgap absorption tails of the polymer semiconductors. A correlation between the extracted width of the density of states and the Urbach energy is presented, corroborating the 2...

the objective of this study was to investigate the relationship among body weight and fat-tail measurements with fat-tail weight by using multiple regression and principal component analysis. the eleven characters includes, body weight, fat-tail length, fat-tail circumference, width and diameters in 3 position of upper, middle and lower before the slaughter, and also fat-tail weight after the s...
